To ALL WHoMIT MAY ooNeERN:V

Be it known that I, FRANK LIVINGSTON, of Marathon, in th county of Cortland, and State of New York, have invented a new and useful Improvement in Gates; and I do hereby declare that the following is a full,

clear, and .exact description of the construction and operation of the same, reference being had to the accom-v panying drawings, making a part of this specification. The object of' my invention is to provide a swing-gate which may be readily raised or lowered, to accommodate itself to snow or other obstructions. Y

A is any ordinary gate, swinging between the posts B and C, and hung upon the long hinges DD', so that the gate may be raised' or lowered thereon. F is along bar o r lever, extending lengthwise of the gate, and

hinged .to the gate-post C at Gr. At or near the :entre of this bar is a. pvot, h, firmly fixed in the gate, and

extending through a slot, I, in the bar, and uponlwhich pivot the bar turns or slides readily. u This bar is used 'as a lever, and is the means by which the gate is lowered or raised upon its hinges, being operated at that end of the gate which swings; and'when the gute is raised or lowered to the desired point, the bar or lever ishheld in place by springs or pins in the gate e e As the gate swings, the bar F swings with it, the slot in the bar allowing of any vmovement in the bar which may be'necessary, in consequence of the bar and gate swinging from different centres. Such vslot also allows of the freeupward and downwardJnovement of the lever upon the pivot, and allows theehange of fulcrum as becotes necessary. What I claim,and desire to secure by Letters Patent, is-

The bar Il', hinged and pivoted as described, in combination with the gate and sliding hinges D D, for the uses and purposes set forth.
